| 摘 要： | 采用冲击实验、拉伸实验、超景深三维显微镜、扫描电镜和分光光度计等手段，对PVC／SBS／MBS三元共混体系的冲击强度、拉伸强度、形态结构以及光学透明性等进行了研究。实验结果表明，MBS能有效改善PVC／SBS共混体系的界面相容性。当SBS和MBS的总量不变时，随着MBS相对含量的增加，共混体系的缺口冲击强度逐渐增加，透光率在m（MBS）／m（SBS）=28／80时达到最大值，光学透明性能最好。

| Abstract: | The impact strength, tensile strength, morphological structure and optical transparence of PVC/SBS/ MBS blend were studied by means of impact test, tensile test, optical microscope, SEM and spectrophotometer. The results showed the addition of MBS to PVC/SBS could improve the interfacial compatibility of the blend. When the total content of SBS and MBS was kept unchanged, the notched Izod impact strength of PVC/SBS/MBS blend increased with the increase of the content of MBS, and the transparency of the blend reached to the maximum value when the mass ratio of MBS/SBS was 20/80, having the best optical transparence. |
